Facebook Ad Library Advertiser Search API

Returns the advertisers in Meta's public Ad Library that match a name, username or Page ID, as its search box suggests them. Each has its Page ID (the ID its ads are filed under), name, username, picture, category, country, verified badge and exact follower count, plus the Instagram account Meta links to it with that account's exact followers and badge. Send a country to rank the matches for it.

200 OK · GET https://socialtap.dev/v1/facebook/search_advertisersLong arrays and strings are shortened here. Real responses are complete.Docs

One schema on 27 platforms.

The response reference lists every field, its type and when it is null. See the full schema.

Null means unknown
A field Facebook Ad Library doesn't show is null, never zero or an empty string, so a real zero always means zero.
What it accepts
An advertiser's name or part of it, its Facebook username or its Page ID (never its profile ID), as typed into the Ad Library's search box, in any language (baileys, コカ・コーラ, 20531316728).
Write one parser
Facebook Ad Library, TikTok, Instagram and 24 more platforms answer in these fields, so the code that reads one reads them all.

platformstring: Platform ID (tiktok, youtube, …).
idstring: Platform-native account ID (string; YouTube UC…, Reddit t2_…).
usernamestring: Handle without the @; null when the account has none.
display_namestring: Display name, channel title or page name; null when empty or not exposed.
urlstring: Canonical profile URL.
typestring: Coarse account kind, as the platform labels it; unknown when it does not (TikTok labels organizations only). New values may be added; treat unknown values as unknown.
biostring: Profile bio, channel description or page about text; null when empty or not exposed.
avatar_urlstring: Profile picture URL (largest available). Platform CDN URLs can expire within hours.

What teams build with the Facebook Ad Library Advertiser Search API.

Find a brand's Page ID to pull its ads
List a brand's regional Pages
Link a Facebook advertiser to its Instagram
Vet an advertiser's badge and audience

Good to know before you build.

The search box returns one short list with no further pages, and a full list ends with page.end_reason platform_limit: type more of a name to reach other matches.
id is the Page's own ID, the one the Facebook Ad Library Advertiser Ads API and an ad's advertiser.id use (platform_specific.facebook.page_id repeats it). Facebook's posts and comments name a Page by its profile ID, so join them to an advertiser by username, not id.
metrics.follower_count is exact. A brand's regional Pages often share one global count.
The box ranks by exact capitals (amazonjp and AmazonJP return different lists), and a single Latin letter finds nothing.
type is unknown, because Meta's own label (platform_specific.facebook.ad_library_entity_type) calls a brand's Page and a person alike PERSON_PROFILE.
An advertiser that exists only on Instagram or WhatsApp has no Facebook profile: its ad_library_entity_type is IG_ADS_IDENTITY or REGULAR_PAGE, its url is its Ad Library page, and an Instagram one's audience is in instagram_follower_count.
The box suggests Pages whether or not they ran ads, and the Facebook Ad Library Advertiser Ads API returns an empty list for one that hasn't.
Bios, links and creation dates are null or empty, as the search box doesn't show them: the Facebook Profile API returns them for an advertiser with a Facebook profile.
